nv50: when destroying a channel make sure it's not still current on PFIFO
We won't get a PFIFO context switch when the same channel ID is recreated if
the hw still thinks the channel is already active, which causes fun issues.
Should allow X to be stopped and started without tearing down the entire
card state in lastclose().
